Interior is sent into along the air curtain air outlet after reason.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is that a kind of jet stream disclosed by the utility model purifies air curtain structural schematic diagram；Fig. 2 is in terms of direction of air outlet
The side structure schematic view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, this neighborhood those of ordinary skill is without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model embodiment discloses a kind of jet stream purification air curtain, compares regular air curtain more energy-saving clean.
Fig. 1 shows a kind of jet stream purification air curtain, including centrifugal blower 1, jet pump (extraneous incoming flow air inlet 4, nozzle
5, diffuser pipe 7, trunnion 9 collectively form), pod 2, fresh air purification device 3, heat-exchanger rig 6, air outlet 8 and be placed in the dress
Set external shell (not shown), in which:
The centrifugal blower 1 is connected with the pod 2；
The pod 2 is connected to jet pump high-velocity fluid inlet；
The fresh air purification device 3 is set at the jet pump external fluid air inlet 4；
The heat-exchanger rig 6 is set to 9 middle part of jet pump trunnion.
For ease of understanding, operation principles combination Fig. 1 of jet stream purification air curtain is illustrated:
Start centrifugal blower 1, bring into operation with the jet pump, high-velocity fluid is sent out by centrifugal blower 1, through pod 2
Jet stream pump suction chamber is imported, and flows through nozzle 5 to trunnion 9.5 exit of nozzle is due to surrounding air is swept away by jet stream during this
Vacuum is formed, outside air is inhaled into due to draught head.Outside air enters from extraneous incoming flow air inlet 4, in fresh air purifying
Purification filtering is carried out at device 3, high-velocity fluid is completed to mix and carry out momentum-exchange at trunnion 9, be made defeated with extraneous incoming flow
The kinetic energy of extraneous incoming flow is sent to increase.
Fluid-mixing kinetic energy at the trunnion 9 increases, and after completion temperature adjusting at heat-exchanger rig 6, passes through
